IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 183,6 [2, dated October24,1876; application filed July 1, 1876.

To all whom it may concern:

Be it known that I, EBENEZER GLADDEN WHITING, of Northfield, in thecounty of Rice and State of Minnesota, have invented certain new anduseful Improvements in Plows, of which the following is a specification:

This invention relates to plows; and consists in making the frame forsupporting the share, mold-board, land-side, &c., of one single piece ofsheet steel, cut in a peculiar shape, and bent and welded into theproper form in suitable swages, &c., as hereinafter set forth; also incertain other improvements that will be hereinafter set forth.

In the drawings, Figure 1 is a side elevation, and Fig. 2 is a planview, of a plow with my improvements attached thereto. Figs. 3 and 4 areviews of the shape in which the sheet steel will be out to form theframe, &c. Fig. 5 is a perspective view of the frame inverted, showingthe manner of securing the beam thereto. Figs. 6, 7, and 8 areperspective views of the two parts of the frame.

In my improved frame I use one single piece of sheet steel, cut in theshape shown in Fig. 3, which is then bent in a suitable machine or swagealong the dotted lines, to bring the two edges on b together, when theywill be welded and drawn out sharp, which will cause the frame to assumethe form shown in Figs. 5 and 6. By this means the complete frameisformed, 0 being the base for the share d and moldboard 0; f, the basefor the land-side g,- and h, the fiat top, to which the beam A will beattached.

By this simple device I form the complete frame of one single piece ofsheet steel, and with only one weld, and, consequently, it can be mademuch lighter and cheaper than by the old method. To strengthen it,however, I propose to weld into the nose or forward end of the frame anauxiliary piece, B, Figs. 7 and 8, which serves to stiffen it at thatpoint where the greatest strain will occur. By this arrangement theframe will be very strong, even with a very light quality of steel, andwill also be in consequence much lighter than the old st le.

illhis combined lightness and strength is a very great advantage, as itenables a very light plow to be used in very heavy land, and will,

in many cases, dispense with the necessity of an extra heavy plow forheavy soils. It will also be much more convenient to handle and moveabout, while its great simplicity will enable me to manufacture it at agreat saving in cost and time.

As before mentioned, the flat surface h, forming the top of the frame,serves as a base, to which the beam A is secured. The back end of thebeam is curved in a semicircular form, as shown, and is bolted to thebottom side of the top it of the frame, as shown. By this means theframe is made to pass back of and above the mold-board c.

When the center of draft has been determined the enlarged portion D ofthe beam A where it is secured to the frame will be made to fit thesidef of the frame, so that every beam will fit in exactly the samespot, and thus insure a uniformity in their arrangement,

and enable the beams to be made interchange- Y able, and thus duplicatescan be readily furnished.

E is a brace, made of sheet steel, and placed beneath the back of themold-board, with one end secured thereto, while the other end is securedto the land-side frame f. (See Fig. 2.) This acts as a brace or supportto the moldboard, while at the same time, by being made of sheet steeland completely filling the angular-shaped cavity formed by themold-board and land-side, it also acts as a shield or guard to preventany earth or other matter from getting into the hollow space beneath themoldboard. Gr G are the handles, which are secured directly to the beam,as shown.

The advantages 1 claim for this arrangement are, that it removes thestrain from the frame, and thus enables me to use a much lighter onethan would otherwise be the case. It also enables me to use shorterhandles, thus making a saving of about two feet of length of handles. Italso enables the plow to be handled with much greater ease, as thehandles, being fastened well back, act as levers in turning the plow, oroperating it.

In ordinary plows the colter is secured to the beam, and in somecast-iron plows it has been cast in one piece with the share. In thelatter shape it possesses the advantage over the former of cutting thesod and lifting the furrow at the sametime. This insures an easyworking. of the plow.

I weld the colter H fast to the steel share, and in the same form as inthe cast-iron ones; but, being of steel, it can be made as thin as isnecessary to work nicely in the soil. I thus preserve all the advantagesof the position of the cast-iron colter, with the lightness and strengthof the ordinary suspended coltelf.

What I claim as new, and desire toseeure by Letters Patent, is-

1. The plow-frame c f h made of one piece of metal; cut-intheshapedescribedandlshown and bent by suitable means into a supporterseat for the mold-board, share, land-side, and I beam of the plow,substantially as shown and described, andzforthepunposessettforth.

2. The auxiliary.- piece, Benin. combination with the frame 0 fh, and-weldedor otherwise secured thereto, as hereinbefore described.

3. The combination and. arrangement of the curved beam A, frame a f h,and handles G G, as hereinbefore set forth.

4. The curved. shield'iandahrace E, in combination with the mold-board eand land-side frame fi a s and for the purpose hereiubefore explained:

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witmesses.
